INTRODUCTION

Building on the outstanding legacy of the Millennium Series, Net Safety’s latest innovation in this line of continuously evolving industrial transmitters and sensors, the Millennium II, pushes the boundaries of what you can expect from your detection system. Combined with state of the art “Smart” sensors, users will receive a detection system which is both versatile and reliable for fast, accurate and continuous monitoring of gases in extreme environments.

THE PRODUCT

TRANSMITTER/CONTROLLER

A Millennium II gas detection system is composed of a field mounted transmitter\controller and Millennium II series sensors which may be integrally mounted to the controller or remotely mounted as far as 2000 feet away.

The transmitter is certified for use in hazardous locations and is available as a single or dual sensor system. All operator controls including configuration and calibration can be accessed without opening the enclosure by using other communication devices and the attached magnet to actuate reed switches. If the area is non-hazardous and the enclosure (housing) is open then the operator may choose to use push-button switches and analog output test jacks on the face of the electronics module. Available outputs are: conventional 0.0 to 20mA analog, Analog/HART, electromechanical relays, solid-state relays or Modbus RTU digital.

A dual channel transmitter is available with "peak picking" functionality where there is only one analog output and this analog output follows the signal from the sensor that is responding to the highest gas concentration. This is useful in conserving analog input capacity on connected user equipment.

THE MANUAL

This manual has been designed to guide users through each procedure, ensuring that transmitters and sensors are configured, operated and maintained properly. Guidelines and warnings are included to ensure safe and proper functioning of the equipment. The manual gives the overall operational and functional features of transmitters with sensors and may not have sensor specific information. Refer to sensor manuals for information specific to each sensor including detailed calibration instructions. If you encounter any problems, see the troubleshooting section of this manual or contact factory.
